Embodiment:
The present invention is described in detail below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4.
But a kind of three interlocking line block diagrams of motor forward/backward rotation timing automatic conversion operation control as shown in Figure 1, motor forward/backward rotation control main loop circuit figure as shown in Figure 2, often the opening of inner each group of the on-delay time relay self, normally-closed contact connection layout as shown in Figure 3, motor forward/backward rotation control loop circuit diagram is as shown in Figure 4.In Fig. 1, timing control unit is made of the on-delay time relay, the motor forward/backward rotation control loop is realized with the routine techniques means, it is controlled switching on and off of different contactor main contactss and realizes that control Motor Control major loop prograde circuit or circuit for reversing are switched on or switched off, three interlock circuits by two groups of the on-delay time relay self inside often open, normally-closed contact and contactor KM1 and KM2 normally-closed contact separately form.Fig. 2 is conventional motor forward/backward rotation control main loop circuit.Fig. 3 is the structure of the present invention's often opening of requiring that inner each group of the on-delay time relay self should have, normally-closed contact, wherein side a and b maintains static, the C end is removable for common port, C holds or shift to the A end makes A-C be communicated with (this moment, B-C disconnected), C holds or shift to the B end makes B-C be communicated with (this moment, A-C disconnected), the situation that A-C and B-C are communicated with simultaneously will not occur, two in three interlock circuits of the presently claimed invention interlockings by two groups shown in Figure 3 often have open, the structure of normally-closed contact consists of.Fig. 4 is motor forward/backward rotation control loop circuit diagram, and three interlock circuits just are included among Fig. 4.But a kind of three interlocking lines of motor forward/backward rotation timing automatic conversion operation control are made of Fig. 2 and Fig. 4.
In Fig. 4, SB1 and SB2 are push-button switches, and KM1 and KM2 are contactor coils, KM3 is relay coil, and KT1 and KT2 are the on-delay time relay coils, and FU1 is fuse, FR is the control contact of thermal relay among Fig. 2, and physical circuit connects as follows: see that summary of the invention is described.
The specific works mode is as follows:
Such as Fig. 2, shown in Figure 4, suppose KM1(KM2) motor forward (counter-rotating) during the main contacts adhesive of contactor, before actuating motor rotating operation, set first the delay time of on-delay time relay KT1 and KT2.Slightly stop a moment after pressing the button SB2, then unclamp the SB2 button, the KM3-1 of KM3 relay, two normally opened contacts of KM3-2 close, the KM3 relay coil keeps energising, and contactor KM1 coil electricity, motor begin the forward power supply, KT1 coil electricity and KT1 begin regularly, two normally-closed contacts of KM1-1 and KM1-2 disconnect KT2 coil blackout, KM2 coil blackout; When the KT1 timing then, KT1-1 and KT1-2 normally-closed contact disconnect first, then KT1-1 and KT1-2 normally opened contact close, contactor KM1 coil cuts off the power supply first, then KM1-1 and KM1-2 normally-closed contact close, contactor KM2 coil electricity, motor stop to begin the counter-rotating power supply after the forward power supply, and the KT2 coil electricity also begins regularly; When the KT2 timing then, the KT2-1 contact disconnects, the KT1 coil blackout also makes KT1 reset to initial condition, KT1-1 and KT1-2 normally opened contact disconnect first, then KT1-1 and KT1-2 normally-closed contact close, the KM2 coil cuts off the power supply first, then the KM2-1 normally-closed contact closes, and KM1 coil electricity, motor stop to begin the forward power supply after the counter-rotating power supply, two normally-closed contacts of KM1-1 and KM1-2 disconnect, the KT2 coil blackout also makes KT2 reset to initial condition, and the KT2-1 normally-closed contact closes, and the KT1 coil is switched on again, KT1 begins again regularly to repeat the process of front; Motor is constantly carrying out rotating and reverse operation according to KT1 and KT2 timing.When the needs motor is out of service, press the button and slightly stop behind the SB1 a moment, then unclamp the SB1 button and get final product.
In Fig. 4, two normally-closed contacts of KT1-1 and KT1-2 are serially connected in the KM1 path of winding, two normally opened contacts of KT1-1 and KT1-2 are serially connected in the KM2 path of winding, because KT1-1 often opens, normally-closed contact and KT1-2 often open, closed simultaneously phenomenon all can not occur in normally-closed contact, sequencing must be arranged, see Fig. 3, so the simultaneously phenomenon of energising just can not occur in KM1 coil and KM2 coil, therefore, the phenomenon of Motor Control major loop short circuit when automatically changing with regard to the rotating of Motor Control loop can not occur, because KM1(or KM2) KM1-1(or KM2-1 during coil electricity) normally-closed contact disconnects, can guarantee KM2(or KM1) coil cuts off the power supply, therefore, motor just (or anti-) turn run duration and also can guarantee the phenomenon that the Motor Control major loop is not short-circuited, thereby, utilize often opening of KT1-1, normally-closed contact and KT1-2 often open, the normally-closed contact of normally-closed contact and KM1-1 and KM2-1 can be realized triple interlockeds of KM1 coil and KM2 coil electricity are used.
But three interlocking lines of a kind of motor forward/backward rotation timing automatic conversion operation control of the present invention except can be used for motor forward/backward rotation timing automatic conversion operation control, also can be used for the unidirectional operation control of motor through simple process.
